Damm (11-6) was expected to face Hacran Dias (21-2-1) in a featherweight bout in Barueri, Brazil, but suffered from kidney stones while cutting weight for the fight. With four days remaining until the event, the UFC decided to remove Dias from the card.
Damm has had previous issues with weight-cutting. After two wins at TUF: Brazil 1, the featherweight was forced to leave the show in the semifinals, when he was expected to meet Hugo Viana, when he suffered from kidney problems.
With the change, the first bout is expected to start at 5 p.m. ET.
